SPOKE-THROATING MACHINE.

SPBCIPICATIONforming part of Letters Patent No. 340,909, dated April 27, 1886.

Application filed January 30, 1886. Serial No. 190,288. (No model.)

To all whom, it 11mg concern:

Be it known that I, WILLIAM H. DOANE, a citizen of the United States, residing at Oincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Spoke-'llhroating Ma chines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Spoke-throating machines are known which throat spokes on both sides simultaneously by means of two oscillating cutter-heads, no reversal of the spoke being required. Other spoke-throating machines are known which are adapted to throat the two sides of a spoke successively by means of two fixed cutterheads, but which require the reversal of the spoke after one side has been throated and before the other side can be throated.

My invention consists, as a whole, of a machine so organized with two fixed cutter-heads that it can throat thetwo sides of a spoke successively without requiring the reversal of the spoke.

In order that my invention may be clearly understood, I have illustrated in the annexed drawings, and will proceed to describe, a practical form thereof.

Figure 1 represents a front elevation of this spoke-throating machine. Fig. 2 represents a side elevation thereof. Fig. 3 represents a plan of the same. Fig. 4 represents a front elevation of a portion of the machine, and illustrates how the spoke is held in traversing it past the respective cutter-heads.

The same letters of reference indicate identical parts in all the figures.

In the machine shown in the drawings one of the cutter-heads is arranged in advance of the other, so that both sides of the spoke can be throated during a single pass of the spoke through the machine. This is an advantageous arrangement, but not a primary necessity. Gutter-h ead A is secured to a. horizontal shaft, A, which is journaled in bearings of a slide, A mounted on vertical guide-rails c on the front side of frame or column 0. Slide A is held in position vertically, and can be adjusted vertically by a screw, A Gutter-head Bis secured to a horizontal shaft, B, which is journaled in bearings of a slide, 13 mounted on vertical guide-rails 0 on the front side of an upward extension, 0, of column 0. Slide B is held in position vertically, and can be adjusted vertically by a screw, B SlideA has a bracket-arm, a, projecting alongside cutterhead A. An angle iron or foot, a, is fitted in a horizontal guideway on bracket-arm a, and is secured thereto by a clamping bolt, a which passes through a horizontal slot in the sole plate of the foot, so that the latter can be adjusted horizontally along the bracket-arm, in order to bring the heel-plate of the foot to the desired position with reference to the outer end of the cutter-head A, which end it faces. A spoke-guide, D, is secured to the heel-plate of foot a by clamping-screws cl d, which pass through vertical slots d d in the spoke-guide, so that the latter may be vertically adjusted to bring its curved upper edge to the required position with reference to cutter-head A. Slide 13 has a similar bracket arm, b, on which a similar foot, I), is adjustably mounted, the same as foot a is mounted, and a similar spoke-guide, E, is adjustably secured to the heel-plate of foot I), in reverse position, however, so that the lower edge forms the spokeguiding edge. Outterhead shafts A and B are provided with pulleys for driving them in opposite directions by suitable belt gearing.

The spoke is supported upon and fed through the machine by the spoke-carriage F, which is hinged on the fixed rod G, on which it also slides. Rod G is secured to posts G G,which are in turn secured in sockets or eyes on arms C and O of column 0. The posts G are secured by set-screws, so that they may be adjusted to raise the rod G to the proper heightnamely, to such height that its axis will lie in a' horizontal plane about midway between the respective horizontal planes of the axes of the cutter-heads. This arrangement of the rod G with reference to the axes of the cutterheads is important, because it insures a like, though reverse, presentation of the spoke to the respective cutter-heads, so that the spoke will, be throated alike on both sides.

In the machine shown the cutter-heads are so close together that the rear end of spokeguide D projects beyond the front edge of spoke-guide E, in consequence of which a vertical clearance-space must be left between the spoke-guides, in order that the spoke may be lifted from spoke-guide D to a sufficient height to permit it to properly follow spokeguide E. To provide for shaping the spokes alike under these circumstances, the cutterheads are so adjusted that the spoke, in presenting it to the lower cutter-head, will have a downward inclination alike in degree to that of its upward inclination on presentation to the upper cutter-head, as indicated in Fig. 4. It is obvious that cutter-head A may be placed so far in advance of cutter-head B that the spoke can be presented horizontally to each. In all cases the cutter-heads are so arranged with reference to the spokecarriage as to be on opposite sides of the plane or path along which the carriage moves the spoke.

The spoke-carriage is provided with a spokeclamping lever, H, for clamping the tenon of the spoke down on the bar f of the carriage, and with the usual adjustable knee, I, against which the body of the spoke rests. A handle, f, on the spoke-carriage near knee I projects under the spoke, so that the operator in pushing the carriage forward may hold the spoke and handle grasped with his right hand,while he holds the clampinglever depressed with his left hand. A rail, 0', is provided on column O, for supporting the free side of the spoke'carriage in either of its extreme positions. The spoke-carriage may be counterbalanced by a weighted arm, F, as shown.

The machine is adjusted to different sizes of spokes by vertical adjustments of the cutter-head slides. It will be understood that with cutter-heads of given form the shape of the throats is determined in part by the spoke guides, and in part by the transverse contour of the spoke where it traverses the spokeguides.

I do not confine myself to the particular style of spoke-carriage shown and described, as other known styles of spoke carriages,

whether hinged or not, can be readily substituted for the one illustrated; nor do I confine myself, primarily, to other details of construction, because they may be much varied Without departure from the fundamental characteristics of my invention as generally set forth in the recital at the beginning of this specification, and distinctly pointed out in the first of the ensuing claims.

I claim as my invention- 1. The combination, substantially as before set forth, of a spoke-carriage, two fixed cutter-heads, which are arranged, respectively, on opposite sides of the plane or path along which the spoke is moved by said carriage, and a fixed spoke-guide on each cutter-head slide, whereby the two sides of a spoke can be throated successively without reversing it.

2. The combination, substantially as before set forth, of a spoke-carriage, two fixed cutter heads, which are arranged one in advance of the other, and respectively on opposite sides of the plane or path along which the spoke is moved by said carriage, and a fixed spokeguide on each cutter-head slide, whereby the two sides of a spoke can be throated successively at a single pass and without reversing the spoke.

3. The combination, substantially as before set forth, of a hinged spoke-carriage, two fixed horizontal cutter-heads, which are arranged, respectively, on opposite sides of the plane or path along which the spoke is moved by said carriage, a screw applied to the supportingslide of each cutter-head for vertically adjusting the same, and a fixed spoke-guide on each cutter-head slide.

In testimony whereofI affix my signature in presence of two witnesses.
